Version 0.78p

Fixed bug that caused the cooling fan PWM frequency to be 165kHz. It is
now 25kHz.
Fan RPM is now included in the web interface status response (thanks
zpl).
Many more error messages are now reported to the web interface as well
as the USB interface.
Interrupt-driven network timer task to better cope with slow SD card
writes (thanks zpl)
Module SamNonDuePin is now used for all digital and PWM pin I/O.

 * When using a Z probe, Z homing and bed probing are done in two stages (a fast stage followed by a slow stage) for better accuracy.
 
+* The default initial Z homing and bed probing speed has been increased. This is possible because Z homing and bed probing slow down when the probe reading is approaching the target value.

 * M116 takes an optional P parameter to specify which tool to wait for. If no P parameter is given, it waits for all tools and the bed as before. The main purpose of this is that on a tool change, you can wait for the new tool to heat up to operating temperature but not wait for the old tool to cool down to standby temperature.

There is currently a bug in the M135 (set heat sample interval) command, which means that if you change the interval from its default value of 0.5 seconds then you need to adjust the I parameter by the same ratio and the D parameter by the inverse ratio.
